A yellow box is used if someone creates a newbie-warning flag, which on the "Add flag" page reads as follows: Due to various concrete red flags, I believe that anyone dealing with this user has a high risk of losing money. (This flag will only be shown to guests/newbies.)

A red box is used if someone creates a scammer warning flag, which on the "Add flag" page reads as follows: This user violated a casual or implied agreement with me, resulting in damages. or This user violated a written contract with me, resulting in damages.

Your trust ratings are irrelevant to the displaying or coloring of the flags.

If someone has an active yellow colored newbie warning flag, they will display a # next to their trust scores and a warning box to all guests and newly registered (under 7 days logged in time) users.
If someone has an active red colored scammer warning flag, they will display a !!! next to their trust scores and a warning box to all users.

A newbie-warning flag is active if there are more people supporting such a flag than opposing it. It shows a banner on topics started by the flagged user for guests and for users with less than 7 days of login time. For all users, a "#" is shown next to their trust scores.

For contractual violations only, a scammer flag can be created. This is the only thing which causes the "Warning: trade with extreme caution" warning to return. It also triggers a banner similar to the newbie-warning banner which is visible to all users. A scammer flag requires 3 more supporting users than opposing users to become active.

As I mentioned in the flags topic, there are three very separate scopes for trust which need to be kept separate. For scammer flags, the point is to damage the person's forum existence in order to deter future scamming. This is a very serious action which should have a very high bar. Because it's so serious, I only want actual agreements considered here. In legal systems, there's additionally such a thing as tort law and statutory law, but the forum is very far from having the kind of cohesive legal system which could handle such things in a halfway-reasonable way. The only thing that approaches clear-cut scamming is violation of an agreement. If non-contractual offenses are allowed in the scammer-flag space, then we're going to get factions of forum users constantly fighting each other, which is exactly what I'm trying to stop. I'm sick and tired of big escalations and never-ending feuds over highly-subjective and/or relatively minor things.

For non-agreement issues, use a newbie-warning flag and give them a negative trust rating. These actions are in the different scopes of warning newbies or informing other users of your opinions, which have less severe consequences and therefore lower bars.

I hate having to "defend" BSV and BCH, which were created with deception in mind, are technologically bankrupt, and are run by huge assholes, but you can't say that their supporters broke a contract with you when they didn't. Give them a newbie-warning flag if you want, but not a contract-violation flag unless they actually broke a contract with you. (Note that you might have a case for breach of implied contract if you were actually tricked into buying one of these coins instead of BTC.)

Normal font is displayed for users who are on your own personal trust list. Small, italic, grey font is for users who are not on your own personal trust list. If you do not have a personal trust list, then default trust is used. You will always appear as normal to yourself.

I can put a flag on my own account. This should be disabled as before.

I think the code of trust score should be Bolded on the profile to be more effective
